WRX-John

I have a squeek when I back off to change gear in 1st, 2nd, 3rd when driving off boost, when driving quick it doesn't do it so after many people looking at it and coming up with the rear beam bushes I took it to the dealer to price them up. After 20 mins they had priced up every bush and shocks on the rear end told me it will be £70 per hour to do plus vat and it could even be something on the front end gone, they was very helpfull but I could see a hefty bill I bound if I said yes try and find it. Soooo I've decided to go to the clinic and let them sort it, my cars got lots of history from there so they must be good (hopefully). I just hope those guys can sort it as it's driving me mad
